I got some subs on this last week but it wasn’t really enough to do much with. This is the first time I managed this one properly and it’s some processing task! It’s taken me about 4 hours to get to this point, I had to learn layer masking for the core detail using 60 sec subs and had some really big problems getting my flats to work and the subsequent gradients that happened. A combination of Noel’s Actions and more layer masking saved the day

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 2,500,000 light-years away in the constellation Andromeda. It is the nearest spiral galaxy to our own, the Milky Way. As it is visible as a faint smudge on a moonless night, it is one of the farthest objects visible to the naked eye, and can be seen even from urban areas with binoculars. It is named after the princess Andromeda in Greek mythology. Andromeda is the largest galaxy of the Local Group, which consists of the Andromeda Galaxy, the Milky Way Galaxy, the Triangulum Galaxy, and about 30 other smaller galaxies. Although the largest, Andromeda may not be the most massive, as recent findings suggest that the Milky Way contains more dark matter and may be the most massive in the grouping. The 2006 observations by the Spitzer Space Telescope revealed that M31 contains one trillion stars, several times more than the number of stars in our own galaxy, which is estimated to be 200-400 billion.

  1. Stunning image! I just bought the Sky Watcher Equinox 80 so I can’t wait to start bringing in astrophotos.

  2. Very nice work Euan!

    I’m thinking about an Equinox 80 myself and found your image via Google image search 🙂

    All the best,

    Mike
